UPDATE: Official trailer here, as noted by Chris M.

I do agree that the action scenes look a bit too wild and extreme for the period—I'm simply not buying an original-Trek-era Trek where everything crashes around so frenetically in space; perhaps it's "realistic", sure, but "action scenes" in TOS and the TOS-era movies generally meant a lot of on-screen tactical graphics and people falling down on the bridge, interspersed with one or two careful and ponderous model shots. It wasn't on purpose that it looked so bland and staid at the time; but nonetheless it's what feels right. Sort of. I guess.

But I for one like the casting. Kirk and Spock ring true, at least visually. And I like how they resurrected Tom Paris' gearheadedness (geeks will recall his penchant for classic—and I mean really classic—Camaros) and cast it onto Kirk, with the Corvette he drives in the let's-fake-out-the-audience-who-doesn't-know-what-the-hell-movie-this-is-a-trailer-for childhood scene. It fits the character, more or less.

All I'm really hoping for is that they don't introduce too much in the way of Alien Species And Visual Styles We've Never Seen Before And Will Never See Again, à la Enterprise. Surely there's plenty of story to be had just by focusing on the principals and the state of galactic politics at the time and such. Indeed, if they can't make that into an entertaining movie, they really ought to retire and take up worm farming or something.
